sipXcom review
A free, self-hosted SIP PBX with broad call-control and redundancy features.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
sipXcom is an open-source IP telephony and unified communications system for organizations that operate their own telephony infrastructure. Its browser-based administration covers SIP call control, user and device provisioning, voicemail, auto-attendants, conferencing, presence, instant messaging, and call-detail reporting. The feature set suits small, mid-market, and enterprise organizations that have the technical capacity to run a self-hosted PBX; it is less suited to teams seeking a managed phone service.
Call handling is a central strength: the listed functions include transfer, hold, forwarding, hunt groups, and call pickup, alongside least-cost routing and SIP trunk or gateway support with failover. It also supports redundant call control and geographically distributed configurations. Administrators can deploy service roles on one server or across multiple servers, with web-based configuration and centralized device management. Integrations include Microsoft Active Directory, Microsoft Exchange, Jitsi, CounterPath Bria, and SIP-compliant gateways and trunks. This breadth makes sipXcom relevant where an organization needs control over routing and deployment rather than a narrowly focused calling tool.
The trade-off is operational responsibility and a bounded documented platform footprint. Installation documentation covers Rocky Linux 9 and provides separate instructions for CentOS 7, so teams should assess their environment against those requirements before choosing it. Support channels are community resources and documentation. sipXcom is a better fit for teams prepared to administer Linux-based telephony and maintain their own infrastructure; organizations prioritizing managed operations or a broader documented platform range should consider alternatives. Call capacity is described as dependent on bandwidth and hardware, not as a fixed limit.
